Abstract

The invention relates to the technical field of test equipment, in particular to a rainfall simulation device with an adjustable water outlet hole area and a raindrop erosion simulation system. The rainfall simulation device comprises a hollow round pipe, one end of the hollow round pipe is closed, the other end of the hollow round pipe is provided with an extending hole for a mandrel to extend in, a plurality of water outlet holes are distributed in the hollow round pipe at intervals, the hollow round pipe is provided with a water inlet hole, an arc-shaped plate is arranged in the hollow round pipe, inner holes corresponding to the water outlet holes in a one-to-one mode are formed in the arc-shaped plate, and a connecting plate is detachably connected to the arc-shaped plate at one end of the extending hole; and a hollow shaft is further included, one end of the hollow shaft is connected with one end of a hollow circular tube with an extending hole through a connecting piece, a mandrel is screwed in the hollow shaft, one end of the mandrel penetrates through the connecting piece and enters the extending hole to be connected with the connecting plate, the other end of the mandrel penetrates out of the hollow shaft to be connected with a rotating mechanism, and the rotating mechanism is fixed on a shaft sleeve sleeved outside the hollow shaft. According to the rainfall simulation device with the adjustable water outlet hole area, the water outlet hole area can be adjusted, and the erosion degree of different environments to samples can be simulated.

Description

technical field

[0001] The invention relates to the technical field of testing equipment, in particular to a simulated rain shower device and a raindrop erosion simulation system with an adjustable outlet hole area. Background technique

[0002] As the most widely used and largest category in the field of new materials, fiber-reinforced plastics are widely used in the fields of national economy, national defense and military industry such as wind power, aircraft, and missiles. Fiber-reinforced plastics have many excellent properties such as high specific strength, high specific modulus, and strong designability, but there are also many corrosion problems. When the fiber reinforced plastic itself or its coating, aircraft, missiles, and wind turbine blades move in the rain, the limiting reinforced plastic components such as the leading edge of the wing, the radomes, and the leading edge of the blade will be directly impacted by the raindrops and will be eroded and damaged.
